Application filed February 20,1909. Serial No. 479,174.

To all who/m. it may concern:

Be it known that I, It-ALPH'A. SCHOEN- nEnG, a citizen of the UnitedStates, and a resident of New York, in the county of New York and 'State of New, York, have invented certain new and useful Improvements in .Electric-'Light Sockets,'of which the'following is a' specification, taken in connection forms a part .'o-fthe same` -Thlsmvention' relates 4 to electric light sockets and more particularly to asocket to With the accompanying-, drawing, which which the feed Vwires may be connected With- 4out the aid oie-binding;` screwsxor other simi lar connections and one which is adapted for lamps ot" any candle'power from. the smallest.' to the highest.

lIn the accompanying' drawing showing` .illustrative embodiments ofthis invention fsimilar parts inthe several ig'ures, Figure l 1 `is a .longitudinal vert1cal section through and in which the same numerals refer to portlon- 4ot the lampto cooperate with the socket and a portion ot the base being` shown in side 'elevatiom Fig. is a longitudinal ve'rtical section through the socket and cas- Iingnthe view being rtaken at right angles Ato that shown in Fig. 1. the base and a portion l3th '.elevation..

In .theillustrative embodiments lot this invention fsliown .-in the drawing, v1 is an electric light socket preferably formed ot' a base Zand a 'member'- vsecured to the base in airy suitable manner. erahlymakethe base ol any insulating mate i'la'l such' as porcelain, or other material, and

preferablyy t'orm the member 3 cylindrical with cut awavpoi-tions El?, 37, and press, v stamp or otherwise torni m 1t female screw -threads -l i'or the reception ot the complementary male screw threads .7 upon thelainp t which is adapted, tobe held in the electric In practice I prefi light socket. It is,'of course, to be understood that my invention is not to be limited to the particular cylindrical and screw threaded member 3, for this member 3 may be given any shape or contour to cooperate vwith any complementary locking surface or surfaces carried by the lamp to be held. The cylinder and screw threads shown are merely illustrative locking,` means.

In the simplest form of my invention I provide the base.2, Fig. 5, with perforations or apertures 7 and 8,- for the reception of the ends of the wires 9 and lO respectively. In my invention it is merely necessary. for the operator to remove the insulation from t'h'e bared ends through their respective holes or 'apertures 7 andS, the bared portion being of -suiiticient ieng'th to pass through the base 2 and be bent across its upper facell. In the form shown in Fig. 5, the end 12 of the wire 10, after passing through the hole 8 in the base 2 'is caused to take a posit-ion substantially at right angles to the main portion of the Wire 10, the extreme end bef ing preferably, though .not necessarily, bent down into a side groove 13 in the base 2. The .end 14hA of the Wire 9, after being threaded through the hole 7 is also bent across the face 1I of the base 2, these two ends l2 and Atact with the center contact 15 and the side contact 16 vrespectively of the miniature lamp 17 which is merely shown for purposes ot illustration, for it 'is to be distinctly understood that my .electric 4light socket is adapted to be used With lamps ot' any candle power from :the smallest to the highest.

I1 will be readily seen from an inspection ot' lCig'. 5 that byscrewing the lamp 1T into the shell 3 attached to the base 2, itsI center contact 15 will directly contact with the hai-ed end 120i: the wire 10, while its side contact lo will directly contact with the hared'cnd 1l of the Wire f), and in this manner complete an electrical circuit.A

To conceal `the electric light socket l land to give a more pleasing effect to ythe eye, I preferably, inclose the base 2 4and member 3 within'aglcasing.18 formed of two hollow members'llQ and 2O of different. diameters and? connected together by any suitable i l i i i i i l t l the ends of the wires 9 and 10 and then press 14 being` so arranged as to permit direct'con- '-,means such as by 'fem-aleiserevv; threads l 2:1

upon'the member 20 lafnd male screw threads 22 upon the member 19. When this casin is" used, I preferably `insulate itfrom the'e fect'ric lightsocket by any suitable means such as by rings 23 formed of ber, rlibber or any 'other suitable insule.tion. z-

' vWhile I, in some cases permit the center and side; contacts carried bythe lamp to contact directly With the-baredjwires as shown ,in Fig. 'I may use connecting members between the bar ends of the Wires'and the' contactscar'rie bythelam These members .maybe mounted in any vsuitable manner, but

Il referably mount them u on the lamp soc et locating them on the acev 11 ofthe base 2. show -this arrangement in Figs. 1,' 2, 3 and 4. In this form, the bared ends 12 of the Wire 1 0 is threaded through a hole 38- in thebase 2 `and .is made to pass beneath'the intermediate connecting member2'4. To prevent the Wire being readily pulled out or removed fromthe base2, I 4referably form fthebaredportion l2 of su cient length to permit-its lextreme end, after passing beneath the member 24 to be bent again substantially at right angles to itself to be brought into a groove 25 on one sideof the base 2. This `member 24 maybe of any electrical conduct` ing material and may be mounted in any manner on the base 2 so that it Will bridge thegap between the center contact 26 of the l lamp 6 andthe bared Wire 12, Figs. 1 and 3.

In practice, I preferably make this member 24 out of a strip of metal and .press one end of it 27 into a longitudinal recess 28, formedin the base 2 as clearly shown in dotted lines in Fig. y1. v The free end I bendsubstantially at right angles `to the otherportion 27 until it assumes substantially the position' shown in `Figs. 1 and 3, its extreme end lying over the bared end 12 of the Wire 10 and preferably When in-itsl inoperative position raised a slight distance from theWire, though this is not essential-f In practice I have found good results 'are obtained by making thel member 24 of spring metal though my in-l vention is not limited to any particular Inaterial. The end 14 of the other .Wire 9 I thread through an' opening 29 in the base 2 forming the bared end of sufiicient length to pass beneath a portion of the intermediate connecting member 30. y To more securely fasten the Wire 9 to the base I preferably' have its bared Vend of sufficient length to permit it to be .again bent into a groove 31 in the base 2, similar to the groove 25. This intermediate connecting member 30,- whichf is adapted to make contact between the bared end of the Wire 14 and the side contact 5 of, the lam 6, may be given any shape or con-I tour Whlch will permit it to perform the desired function, though it is to'be understood that in some cases it may be omitted as 3 directly, contacts Velectric light socket Within a casing n shown in 6, Where the side contact 5 'of the 'lamp l6 1s permitted to contact directly With t-he bared end' of the Wire`14. In this latter form the -intermediate connecting member 24 is used as noted, but the intermediate connecting member 30 is omitted.

For purposes of illustration I have shown in Figs. l, 2, 3 and 4 of the intermediate connecting member 30 in the form ofa horse shoe, e'ach side portion 32 being provided.l

-With' a tooth 33 which isa'dapted totake into apertures 34, 34, in the base 2. On the toe of Vthe horse shoe I mount a calk 35 which .With the side contact' 5 of thelamp 6; v

Itis to be understood that my invention is not limited 'to this' particular form-of intermediate connecting member 30. In practice I preferablyform this intermediate connecting member 30 out of thin sheet metal, the

calk 35 being preferably integral with it and islprcferably made by formingea Wing upon -the blank and bending'it back upon itself to v Having thus described this invention iIr connection With the several illustrative em; bodiments thereof to the details of which I do not desireto be limited, what is claimed as nevtr and what it is desired to secure by' Letters Patent is set -forth in the appended claims.
